IMPROVEMENT lN BOTTLE-STOPPE RS.

Specification forming part of Letters Patent No. 108,506, dated October18, 1870.

To all whom it may concern:

Be it known that I, WILLIAM MORGEN- STERN, of the city, county, andState of New York, have invented anew and Improved Bottle-Stopper; and Ido hereby declare the following to be a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being bad to the accompanying drawing,forming part of this specification, in which drawing Figure 1 representsa vertical central section of this invention. Fig. 2 is a plan or topview of the same.

Similar letters indicate corresponding parts.

This invention relates to that class of bot-' tle-stoppers wherein thestopper is attached to a hinged supporting plate or lever; and itconsists of a stopper, made of india-rubber or other suitable elasticmaterial, fastened to a hinged supporting-plate by means of a button,the shank of which is provided with projectin g pins or lugs, and which,when passed up through a slot in the supporting-plate and. slightlyturned, secures the stopper in position, so that when the stopper isworn out it can be readily removed from the supportingplate and replacedby another, all of which will hereinafter more-fully be set forth.

In the drawing, the letter A designates a bottle, on the neck of whichis secured a collar, a. From one side of this collar rises a standard,I), to which the supporting-plate c is hinged, while from the oppositeside of said collar projects an eye, (I. The supportingplate is providedwith a spring-hook, e, and if said plate is turned down over the mouthof the bottle, this spring-hook catches in the eye (I, as shown in Fig.1 of the drawing.

B is the stopper, which is made, by preference, of vulcanizedindia-rubber, and which is attached to the supporting-plate by means ofa button, f. This button is cast of iron, or made of any suitablematerial, and it is embedded in the material forming the stopper, sothat the upper square shoulder of the button firmly retains the stopper.From the shank of said button project two lugs or pins, g, and thesupporting-plate is provided with a round hole to admit the body of theshank, and with two elasticity of the stopper itself prevent ng it fromturnin g.

When the supporting-plate is turned down over the mouth of the bottlethe stopper enters said mouth, and by pressing the plate down until thespring-hook catches under the eye d, the stopper is caused to seal thebottle up hermetically. A slight inward pressure against the end of thespring-hookreleases] the supporting plate, and the stopper flies out,

impelled by its own elasticity, and in some cases by the pressure of thecontents of the bottle.

This bottle-stopper is particularly intended for 'efi'ervescent liquids,which, when the stopper is released, discharge with great force; and bymeans of my stopper such liquids can be easily discharged without dangerof spilling any portion thereof.

If the stopper is worn out, it can be readily removed and replaced by anew one without disturbing the supporting-plate.

- What I claim as new, and desire to secure by Letters Patent, is

The slotted plate 0, in combination with the stopper B, button f, andits lugs g, substantially as described, for the purpose set forth.

This specification signed by me this 13th day of August, 1870.
